False advertising

Highly disappointed at this stage. Quantas SA advertised flights from JHB to Wellington for an estimated R10700. Read the fine print and it stated the valid dates unless sold out prior to that. Went online to book, no option to book the special that is rightbin front of me. Phoned the local Qantas nr to get some insight and the answer is that those dates are not correct as it's the busiest time of the year (March 2018 to Dec 2018). Special doesn't really exist is the other answer. Bithoth answers out of the mouths of Qantas employees. Excuse me, but this counts as false advertising. Even recommending your opposition. I couldn't believe my eyes and ears. Ridiculous. The amount of disappointment and anger is indescribable. How could this be possible and accepted?
